Hi, just yesterday I had flashed some PWM code relating to the PD12-15 pins, and for some reason after that the board would not be recognized by the computer, both on Windows and Linux. If I held down the reset button the computer successfully recognizes the chip and I can upload code to it. Unfortunately the code doesn't do anything once uploaded and the behavior is the same. It registers as an unknown device in Windows.
Now someone on the forums mentioned that if pull the BOOT0 pin up to the supply that it can reupload the code. So it seems to work, but it doesn't now code get's maybe 90% uploaded but always results in error. I have also erased the chip using ST-Link utility. So the problem with detection is not gone away the only way to upload code
This is an example of the error I get:

I am going to see if the windows flasher works properly or not.
Thanks.

Probably this is the STLINK bug with big (>0x1800) Bytes. The USB machines just stalls. Recent git should have this bug fixed by not issuing big transfers. Please retest!
My commit from February 2 "Verify F2 and F4 by using a decent block size" should fix that issue and "works for me". As the issue was opened earlier and the poster didn't react, I propose to vlose that issue.
